Three-point and four-point angular contact ball bearing

The four-point contact ball bearing is a single-row angular contact ball bearing with raceways designed to withstand bi-directional axial loads. Such bearings require less axial space than double-row bearings.

The four-point contact ball bearing has a contact angle of 35, the inner ring can be divided into two pieces, can hold a larger number of steel balls, so it has a larger load capacity, and the bearing is separable, that is, the two pieces of the inner ring and the outer parts of the ball and cage assembly can be installed separately. .
